Wet Rotary Kiln OverviewThe wet rotary kiln belongs to the category of building materials and equipment. It is widely used in metallurgy, chemical industry, building refractories, environmental protection, and other industries. The rotary kiln is composed of cylinder, supporting device, supporting device with baffle wheel, transmission device, movable kiln head, sealing device of kiln tail, coal injection pipe device, etc. The kiln body of the wet rotary kiln is inclined to a certain level. The whole kiln body is supported by a supporting wheel device and has a wheel-retaining device to control the movement of the kiln body up and down. In addition to the main drive, the transmission system is also equipped with an auxiliary drive device which can rotate the kiln body when the source of the main power is broken and prevent the kiln body from bending and deforming. The sealing device of the kiln head and the kiln tail adopts advanced technology to ensure the tightness and reliability of seal.
Wet Rotary Kiln Performance CharacteristicsBecause raw material is made into the mud, it has strong adaptability to heterogeneous raw material, uniform raw material composition, stable process, high quality of clinker, high clinker strength, less dust in grinding process and less fly ash in kiln tail. However, evaporating 30%-40% of slurry moisture in wet production requires a large amount of heat. The energy consumption accounts for 1/2-1/3 of the cost of cement, which is higher than that of the vertical kiln and dry rotary kiln. Because of the high heat consumption, high energy consumption, large water consumption, and water resources consumption in wet production, wet cement production has been listed as a type of kiln that restricts the elimination of cement.
